	* Use of refrigerants in the system. Refrigerants are present in ground source heat pump systems and can pose a threat to the environment as they can be toxic, flammable or have a high global warming potential. However, new types and blends of refrigerants with minimal negative impacts are being developed. A correctly fitted system will also greatly reduce the potential for leakage, which is why using a professional installer is highly recommended.		* Use of refrigerants in the system.

Ground source heat pumps are exclusively powered by the energy of the sun, which heats up the water present in the earth and keeps its temperature constant.

	Alternatively, the Coefficient of Performance (COP) can be calculated by dividing the useful heat output by the electrical energy input. This ratio usually ranges between 3 and 4, making ground source heat pumps extremely convenient for buyers.
